An approach for vehicle detection system from satellite images, which are used in many applications. Vehicle detection is done by pixelwise classification method instead sliding window and region based methods, which are used in existing system. The vital part of the paper is feature extraction and vehicle colour classification. Feature extraction includes edge and corner detection. For edge de...

In this paper a novel algorithm which is based on hamming code and 2 k correction is proposed. The new method also utilizes canny edge detection and coherent bit length. Firstly, canny edge detector is applied to detect the edge of cover image and only edge pixels are selected for embedding payload. In order to enhance security, the edge pixels are scrambled. Then hamming encoding is practiced ...

An image is considered as a set of pixels that are connected in such a manner to form a boundary between two disjoints regions. Typically, the edge detection approach goes through the segmentation process by segmenting an image into regions of discontinuity. Hence it is a technique for marking sharp intensity changes. In this paper, it presents the Ant Colony Optimization based mechanism to com...

In this paper, a hardware system for adaptive Canny edge detection algorithm is designed and simulated for a 128 pixel, 8-bit monochrome linescan camera. The system is designed to detect objects as they move along a conveyor belt in a manufacturing environment, the camera observe dark objects on a light conveyor belt . Here adaptive Canny algorithm is used to increase the accuracy of output obj...

Edge detection is one of the most commonly used and one of the most important operations in image processing which reduces the useless information while retaining the important structural properties of an image. Here a comparative study of Sobel, Roberts, Prewitt, LoG, Canny, Zerocross algorithms are conducted and corner points using Harris Corner detection algorithm on the image are obtained a...

Edge detection from images is one of the most important concerns in digital image and video processing. Edge detection is very useful in computer vision for extracting meaningful information from images. Real time edge detection is implemented on the platform that consists of the TMS320DM6437 DSP, camera, TV tuner, Display and canny edge detection algorithm. The main goal of our technique is to...
